Last year’s top Blue Jays prospect as well, Drabek took more steps forward in 2010, playing the full season in AA New Hampshire. Pitching to a 2.94 ERA and 1.20 WHIP, Drabek threw a total of 162.0 innings. The large number of innings means that if Drabek does indeed start 2011 in the big league rotation, there will not be much need for an innings cap later in the season as Brandon Morrow experienced in 2010, as a full workload of 200 innings is right in line with the Jays general guidelines regarding increasing the workload of pitchers.

At this point, there’s no need to worry about his Tommy John surgery anymore; he’s moved on and has pitched enough since for it not to be a concern.

Most scouts do not consider Drabek to be of ace-material. He is very good at a lot of things but does not possess a nasty out-pitch and does not possess outstanding control or velocity (fastball tops out at 94 and is fairly straight). His 7.3 SO/9 and 3.8 BB/9 rates this year back up this sentiment; neither is too special and lead to a 1.94 SO/BB rate.

That said, Drabek still projects to be an above-average starter, and should put together a string of 3.40-3.80 FIP seasons in the middle of the rotation for years to come.

2. Brett Lawrie

Lawrie came over from Milwaukee recently as the sole player acquired in the Shaun Marcum swap. He was drafted a single pick (16th overall) before the Jays took David Cooper in the 2008 entry draft, and legend has it that Toronto was prepared to take Lawrie had the Brewers not snapped him up first.

Now to Lawrie’s skills. Brett has very good bat speed, and while that hasn’t yet translated into home runs, most scouts assume that he will develop solid 25+ home runs annually (36 doubles, 16 triples in AA in 2010). He also has solid base-running skills and can work a walk.

It’s also important to note that Lawrie was the second youngest full-time player in the entire AA Southern League last year, and he collected his .285/.346/.451 line against players much older than him (average SL age is about 24).

A converted catcher, he’s taken his lumps playing second base, and lots of people within the industry believe that he’ll end up as a corner outfielder in the majors, but I think that much worse athletes have succeeded as infielders, and with hard work, he could become an average second or third baseman.

3. Anthony Gose

The lone player that came over from Philadelphia via Houston in the Brett Wallace deadline sway, Gose may be the fastest player in the minor leagues. He’s stolen 121 bases in his last two minor league seasons (at A and low-A ball), and while he was probably thrown out more than his share of times (a shocking 52 times caught stealing in the last two years), I tend to think that it was the product of tons of pitchouts; with that speed, there’s no doubt teams were expecting him to take off every time he got on base.

To me, plate discipline is perhaps the most important trait of a hitter. To be a good batter, you must work counts and take your walks. And Gose managed to put up a respectable .360 OBP in 27 games with Dunedin after the trade. Most scouts agree that he still has some holes in his swing, and that with good instruction, he could become a .280 hitter (or better) at the major-league level.

With 600 PA, a modest 60 of those walks, the .280 average adds up to a .380 on-base— a good rate for a leadoff hitter.His defense, while still raw, has potential to be plus-plus in centerfield and might have the best outfield arm in the low-minors.

Gose is hardly a finished product however, he’s only 20 and isn’t likely to see the majors until 2013 at the earliest.

4. Deck McGuire

Toronto’s first round draft pick in 2010, McGuire is expected to rise through the ranks pretty quickly, maybe making the majors mid-2012. Some scouts don’t think he has ace-potential because he profiles as a strike-thrower with a slightly-above average fastball and strong out-pitches. His changeup is probably his best pitch, and knowing that the Jays seem to have a formidable reputation of developing changeups, it could certainly become a true out-pitch and vault him to the next level, a la Ricky Romero.

He’ll probably start the year in Dunedin and could finish the season in AA New Hampshire.

5. Zach Stewart

Stewart is surely an interesting case, profiling as a reliever in college and with Cincinnati, but after acquiring him in the Scott Rolen trade, Toronto instantly set their sights on lengthening him out into a starter—which was met with encouraging results in 2010. Sure, his overall 3.63 ERA and 1.96 SO/BB don’t pop out, but down the stretch, he was fantastic, and Keith Law raved about him after seeing him pitch in the Eastern League playoffs.

It remains to be seen what the plan for 2011 regarding Stewart is. If he lights it up in Spring Training and the Jays still don’t have their fifth starter dilemma fully worked out, I could see him making the big leagues immediately. Otherwise, he would probably start the year in AA, as the Blue Jays seem hesitant to put top pitching prospects in AAA due to how batter-friendly the entire PCL is.
